SPECIFICATION forming part of Letters Patent No. 536,602, dated April 2,1895.

Application filed September 1' 7, 1894. Serial No. 523,244. (No model.)I

To @ZZ whom it may concern-.-

Be it known that I, OWEN G. GATES, Jr., a citizen ofthe United States,residing in the city of St. Louis, State of Missouri, have inventedacertain new and useful Improvement in Sash-Fasteners, of which thefollowing,r is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part of this specification,wherein- Figure lis a sectional view of my improved fastener inoperative position on thenpper and lower sashes. Fig. 2 is a similarView, showing a modied form of key for operating the dog or catch. yFig. 3 is a detailed view of the upper sash-section of the fastener.Fig. 4 is a similar view of the lower sashsection of the fastener; andFig. 5 is a crosssectional view of the lower sash-section, as`

taken ou line 5 5, Fig. 2.

This invention relates to anew and useful improvement in sash-fasteners,and consists in the peculiar construction, arrangement, and combinationof the several parts comprising myimproved fastener, as will behereinafter described and claimed.

In the drawings, A indicates what I term the male section of thefastener, which is secured to the upper edge of the meeting rail of theupper sash A. This member of the fastener is in the form of a shell, andis provided with a slot or opening in its face, through which projectsthe tongue portion of a dog B, pivoted therein, said tongue beingreduced at its sides, forming stops, which contact w-ith the edges ofthe slot and limit the outward movement of the dog, but permitting afree inward movement thereof.

O is a spring located within the shell, whose tendency is to hold thedog in its projected position.

A are suitable ilanges by which the section A is secured to the meetingrail of the upper sash.

The other member, D,of the fastener,which I term the female section,consists of a shell D, which is provided with suitable flanges by whichit may be secured to the upper face of the meeting rail of the lowersash D. This shell D is open at its bottom, and projects be- Ywhen bothsashes are closed, as shown in Figs.

l and 2.

E indicates a curtain-wall or partition, which divides the shell DVvertically', said partition being about on the same vertical plane asthe inner side face of the meeting rail. This wall E is formed with anopening e in its lower edge, while on each side of said opening areteeth or projections F. Shell D is provided with an opening or slot clin one of its end walls, through which a key or other device may beintroduced to disengage the dog B from the teeth F, when the parts arein a locked position, as shownin Fig. 1. When the dog is thusdisengaged,either of the sashes may be raised or lowered as the case maybe.

In Fig. 2, I have shown a trigger pivoted in the section D, which, bydepressing the projecting handle, will be forced. in, disengaging thedog from the ra tchet-teeth during the 0peration of raising the lowersash or lowering the upper one.

It will be noted that the dog in the male section is always in readinessto engage the teeth in the female section, whenever the sashes arebrought in such relation to each other that the parts can co-operate.

Having thus described my invention, what vI claim, and desire to secureby Letters Patent, is-

l. In a sash-fastener, the combination with the male section in the formof a shell, which is adapted to be secured to the meeting rail of theupper sash, of a dog pivoted therein, a spring for holding the dog inaprojected position, a female section in the form of a shell which isadapted to be secured to the meeting rail of the lower sash, atoothedportion in said female member with which the dog engages when theparts are in operative position, and a key for disengaging the dog fromthe teeth, substantially as described.

2. In a sash-fastener, the combination with a male section in the formof'a shell, and having an opening in its face, of a dog pivoted in saidshell, the tongue of which dog projects through the opening, a springfor holding the dog in a projected position,r a female section Intestimony whereof I hereunto affix my in the form of a shelha partitionwall nzsaid signature in presence of two Witnesses, this female sectionhaving an opening in its lower 8th day of September, 1894:. edge, teethon each side of said opening, with 5 which the dog in the male sectionis adapted Witnesses: Y
